Switching 230 V with my pc

hello smart peaple :smiley:

A few days i am trying to find a way to get this idea to work, here it comes:
I can control my pc with my iphone and it works smoothly. now i want to water my plants :slight_smile: just for 20 seconds,
and a few more things working on 12V-- to 230 V ~. like a light etc.
I want to do this from a distance by internet on my phone. so when i would have a menu like that dll shown on some pictures,
i am a happy man.

So i found the new k8090 that could switch 8 relais with a usb signal. and asked the question where the dll could be found, well it can’t because the k8090 isn’t on the marked yet.

i dont know that much of this all as you, (i hope) but could someone please tell me what i can do the best for now.

  • wait for the k8090 ( god may know how long that’s going to take)
  • buy the experiment thing (k9055 i think) and a relais kit that can be connected to the k8090.

it would be nice to create a own menu or anything like that for my applications. but i dont know anything of these programms

thank u for your time anyway

greetings: michel

A snippet from the post:

[quote]I’ve written a program for the k8055 that enables you to control the k8055 or a parallel interface.

Controlling and monitoring can also be done by a local network and even the internet.
The data from the interface can be logged analog and or digital.

A screenshot is available on edutechsoft.nl/logscher.html

The program is free and can be downloaded from edutechsoft.nl/logging.html[/quote]

thank you for the reply

i have read the entire post and read the manual. this would work to put 8 channels on or of.

but 80 procent of the programm he made is for checking input signals. i dont need any, but for a noob as me just controling 8 channels will be enough anyway.
still a timer function will be nice. maybe it is in his programm but i couldnt find that. neither in the manual.

when i will activate channel 1 ( digital out 1) i think there is 5 V on the output of the 8055 card.
i found this K8015 its a relais with timer function http://www.velleman.eu/distributor/products/view/?id=341552
but it needs 9 V to operate?? so that wont work then.

what i need to do to make the 5 v output to 230 v output.

Normaly i google everything, sorry for al the quistions. its like going 1 step forward and 2 steps backwards when there is a new idea :wink:

thank u

[quote]when i will activate channel 1 ( digital out 1) i think there is 5 V on the output of the 8055 card.[/quote]There is no voltage output from the K8055. The outputs are open collector NPN transistors. You have to use external voltage.
Here is an example of the connection:

799×410

thank u verry verry much, now i understand it,

this will do the job,

u helped me verry well

2 seps backwords and 4 in the good direction then :slight_smile:

Hi everyone,

What about the Analog output ? Can’t I use this to power the relay ? Or somewhere else I can use the 5V from the USB port ?

I’d like to shut down a power supply (switching 220V) with this USB board. But if I have to attach an external power supply to feed the K8055 board… it kind of beats the purpose.

Thanks for your suggestions

The analog output is not strong enough to drive a relay coil. You can get from it only about 3mA.

[quote]Or somewhere else I can use the 5V from the USB port ?[/quote]You can use this if the relay coil current is <50mA. Connect the +5V from SK2 or SK3 to the CLAMP and connect the relay between digital output and the CLAMP terminal. - Anyhow I do not recommend to use the USB voltage. If you cause a short circuit it may be harmful to your computer.
